Conditions InDepth: Post-traumatic Stress Disorder

Post-traumatic stress disorder
(PTSD) is an
anxiety
disorder that can develop after exposure to a traumatic event or ordeal in which actual physical or emotional harm occurred or was threatened. Events that can trigger PTSD include violent personal assaults, such as rape or mugging, natural or human-caused disasters, accidents, or military combat. PTSD can be extremely disabling.

Many people with PTSD repeatedly re-experience the ordeal in the form of flashback episodes, memories, nightmares, or frightening thoughts, especially when they are exposed to events or objects reminiscent of the
trauma
. Anniversaries of the event can also trigger symptoms. People with PTSD also experience emotional numbness and
sleep disturbances
,
depression
, anxiety, and irritability or outbursts of anger. Feelings of intense guilt are also common. Most people with PTSD try to avoid any reminders or thoughts of the ordeal. PTSD is diagnosed when symptoms last more than one month.
